A radial flow hydraulic turbine whose design is based on a power specific speed, Ωsp=1.707 is to produce 25 MW from a total head, HE=25 m. The overall turbine efficiency ηo=0.92, the mechanical efficiency is 0.985, and the loss in head in the nozzles is 0.5 m. The ratio of the blade tip speed to jet speed is 0.90. Assuming the meridional velocity is constant and equal to 10 m/s and there is no swirl in the runner exit flow,...
